Nishiyama Onsen Keiunkan – World’s Oldest Hotel

The oldest hotel in the world has been operated by the same family for over 1,300 years, even catering to samurai. From its inception, the Keiunkan onsen has been passed down within the original family through the centuries. 52 different generations of descendants have cared for and operated the inn, growing the space and modernizing it slowly with each passing epoch.
